What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment called inlexisertib for individuals with advanced or metastatic solid tumors that have a specific mutation known as RAS/MAPK. Researchers aim to evaluate the effectiveness of inlexisertib alone and in combination with other drugs like trametinib, binimetinib (Mektovi), or sotorasib (Lumakras). The trial consists of two parts: determining the optimal dose and then assessing its effectiveness. Suitable candidates have a solid tumor with a RAS, NF1, or RAF mutation and have not responded to other treatments. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

You may need to stop taking certain medications before joining the trial. Specifically, you must not have taken strong or moderate inhibitors or inducers of CYP3A4 or P-glycoprotein, including some herbal medications, within 14 days or 5 times the medication's half-life. Additionally, you must stop taking grapefruit products 14 days before starting the study.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that DCC-3116, when used alone, is generally safe for patients with certain advanced tumors. Early results indicate it has not caused major side effects in these patients.

When combined with trametinib, DCC-3116 has shown promising results in early lab studies. However, researchers are still carefully monitoring its safety in human trials. Similarly, early research suggests that combining it with sotorasib is also well-tolerated, but more information is needed to confirm this.

In studies where DCC-3116 was tested with binimetinib, it was found to be generally safe, though the long-term effects remain unknown.

Since this study is in its early stages, the main goal is to ensure these treatments are safe for humans. So far, no major safety issues have been reported, but researchers continue to gather data to confirm this. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about DCC-3116 and its combinations because these treatments target specific mutations in solid tumors, like KRAS G12C, which are often tough to treat. Unlike many standard treatments that broadly attack cancer cells, DCC-3116 works by potentially inhibiting specific pathways involved in cancer growth, offering a more targeted approach. This precision could lead to fewer side effects and more effective outcomes compared to traditional chemotherapy. Additionally, when combined with drugs like sotorasib, which specifically targets KRAS G12C mutations, there's a promising synergy that could enhance effectiveness against these stubborn cancer types.

What evidence suggests that this trial's treatments could be effective for solid tumors?

Research has shown that DCC-3116, also called inlexisertib, blocks certain proteins that help cancer cells survive. Early studies found that DCC-3116 is generally safe for patients with some advanced or spreading tumors. This trial will test DCC-3116 both as a monotherapy and in combination with other drugs like binimetinib, trametinib, or sotorasib. For instance, in studies with sotorasib, nearly one-third of patients with a specific type of lung cancer responded positively. Overall, DCC-3116 appears promising, especially when combined with other treatments targeting a common cancer pathway known as RAS/MAPK. ^{1 3 5 6 7}
